空气中的病原微生物容易随气流快速扩散而造成大范围疾病疫情,现有技术方法均难以对其进行快速监测分析。该文以微流控技术为基础,结合空气流体芯片结构设计和液体LAMP扩增方法,构建了一种用于捕获和检测空气金黄葡萄球菌的微流控芯片系统,能在1.5 h内完成分析,结果肉眼可见,具有速度快、价格低和便携的优势,特别适合于对空气气流的现场快速检测。 Pathogenic microorganisms in the air easily spread rapidly with the airflow caused by a wide range of disease outbreaks, the prior art methods are difficult to carry out rapid monitoring and analysis. Based on microfluidic technology and combining with the design of air fluid chip and liquid LAMP amplification, a microfluidic chip system for capture and detection of airborne staphylococcus aureus was constructed, which can be analyzed within 1.5 h , The result visible to the naked eye, with the advantages of fast speed, low price and portable, especially suitable for rapid detection of air flow in the field.
